IMPROVEMENT IN HAMMERS FOR DRESSING STONE.

Specification forming part of Letters Patent No. 158,467, dated January 5, 1875; application filed December 9, 1874.

To all whom it may concern Be it known that I, WILLIAM W. CASTLE, of Belfast,in the county of Waldo, of the State of Maine, have invented a new and useful Im- -krprovement in Hammers for Dressing Stone;

and do lneTeliydeclare the same to be fully described in the following specification and represented in the accompanying drawings, of Which-- Figure l is a top view, Fig. 2 a side view, and Figs. 3 and 4 longitudinal sections, of a hammer-head provided with my invention, which relates to the head formed with one or two recesses, each of them being for receiving and holding, by means of screws and nuts, a series of dressing chisels or cutters.

In the drawings, the chisel-holdin g recesses of the head A are represented at a a, b b being the holes for the passage of the holdingscrews through said recesses. In carrying out have but one eye for reception of the handle, such eye going down through the middle of the head.

By providing the head with an auxiliary eye at its middle, one going laterally through it and crossing the main eye, not only can the handle be used in either of them, whereby the hammer may he often worked to better advantage than if it had but one eye, but each eye affords, with respect to the other, the opportunity of passing a key through it and a notchin the handle, for the purpose of holding, with the eye receiving such key, the handle in the other eye, so as to effectually prevent the head from working loose and flying off the handle while the hammer may be in use.

The hammer-head I usuallymake solid, or

of one piece or block of metal. It may be of cast or wrought iron or steel.

I claim as my invention- 1. In a hammer for dressing stone, the head A, provided with the lips c 0, arranged with each of its cutter-holding recesses a, as and for the purpose set forth.

2. The head as provided with the two handle-eyes e f arranged in it, and to cross each other, all substantially as specified.
